Gerbes的Differential Geometry和Differential Forms

Differential Geometry of Gerbes and Differential Forms

Lawrence Breen

摘要:

我们讨论了某些方面的组合方法的微分几何的非阿贝尔gerbes,由于W。Messing和作者(arXiv:math.AG/0106083),并给出了相关的上循环方程的更直接的推导。这使我们对相应的共边界关系给出了一个更严格的定义。我们还表明,某些局部弯曲和曲率方程的图解证明可以用微分形式的计算来代替。

英文摘要:

We discuss certain aspects of the combinatorial approach to the differential geometry of non-abelian gerbes, due to W. Messing and the author (arXiv:math.AG/0106083), and give a more direct derivation of the associated cocycle equations. This leads us to a more restrictive definition of the corresponding coboundary relations. We also show that the diagrammatic proofs of certain local curving and curvature equations may be replaced by computations with differential forms.
